Dual Channel Ram question


Can someone clear this up for me please. I made the mistake of buying 2x256 dual channel ram when I thought the 512 stick in my tower was dual channel also. Not the case. But my friend said that you can run them all together, but the dual channel wont run at the dual channel speeds, it will just act like regular ram. But others are now saying that they cant run together at all.. Can someone tell me what the truth is because its already being shipped to me and I need to send it back if the case is i cannot use it.

You can run mixed combinations, and it will work like regular RAM.  Your friend is right that it will not give you the speed advantages of dual channel mode, but it should work.

And one more thing, does dual channel mean double the bandwidth?
Dual channel means double the bandwidth (but that doesn't translate to twice the overall computer performance - more like 10%).
